    Abstract

    Generation rescheduling is a cost-effective way to enhance steady-state and dynamic security. The paper presents an improved formulation for generation rescheduling and develops an iterative solution procedure. The proposed method can be used to assist operators to eliminate potential steady-state insecurity, dynamic insecurity, or their combination. Steady-state security is established by the well known Cn - 1) criterion which deals with thermal limits of transmission lines. Dynamic security is defined in such a fashion that transient stability of the system is maintained under any of the contingencies which may occur at each end of every transmission line of a power system. An attractive feature of the proposed method is that it is reliable, realistic and easy to understand since dynamic security is checked in the method by an integration procedure. Simulation results of a 36-machine 200-node practical power system are demonstrated.
